海缆专用聚氨酯保护套弯曲限制器

弯曲限制器包括多个互锁元件，这些元件在受到外部载荷时会铰接在一起并锁定在一起，以形成光滑的弯曲“锁定”半径。选择此半径等于或大于它所应用到的管道的最小弯曲半径。一旦将元件锁定在一起，则存在的弯矩就会传递到元件中，并通过特殊设计的钢界面结构返回到相邻的刚性连接中，从而保护管道/电缆免受潜在的破坏性负载。挠性管，输油管线，电力电缆和脐带缆通常连接到刚性结构，例如海底立管底座, PLEM或井口。为了防止这些管道在柔性和刚性结构之间的界面处过度弯曲，椎骨弯曲限制器通常安装在管道上。VBR特别适用于在管道上作用有静态或准静态载荷的情况，而不是在更适合使用弯曲加劲肋的情况下的动态载荷。我们可以提供定制设计，也可以利用弯曲限流器元件的大量现有设计来适应各种管道，脐带缆和电缆。我们还能够设计和制造所需的钢界面结构。

The bend limiter includes multiple interlocking elements that are hinged together and locked together when

subjected to external loads to form a smooth bend "locking" radius. Select this radius to be equal to or greater than the

minimum bending radlus of the pipe to which it is aplled. Once the components are locked together, the existing

bending moments are transferred to the components and returned 切o the adjacent rigid connection through the

specially designed steel interface structure, thereby protecting the pipes 1 cables from potentially damaging loads.

Flexible pipes, oill pipelines, power cables and umbilial cables are usully connected to rigid structures such as subsea

riser bases, PLEM or wellheads. In order to prevent excessive bending of these pipes at the interface between the

flexible and rigid structures, vertebral bending limiters are usually nitalldl on the pipes. VBR is particularly suitable for

the case of static or quasl-static loads acting on the peline, rather than the dynamic loads when bending siffeners

are more suitable. We can provide custom designs, or we can make use of a large number of existing designs of bending

restrictor elements to adapt to various pipes. umbilical cables and cables. We are also able to design and manufacture

the required steel interface structure.
